Grand Jury Subpoenas Issued in FBI’s Russia Investigation

Federal prosecutors have issued grand jury subpoenas to associates of former National Security Advisor Michael Flynn seeking business records, as part of the ongoing probe of Russian meddling in last year’s election, according to people familiar with the matter. CNN learned of the subpoenas hours before President Donald Trump fired FBI director James Comey.

The subpoenas represent the first sign of a significant escalation of activity in the FBI’s broader investigation begun last July into possible ties between Trump campaign associates and Russia.

US Attorney Dana Boente, whose office issued the subpoenas, is also leading the investigation into WikiLeaks and the effort to bring possible charges against the group’s founder, Julian Assange. Boente is also acting as head of the Justice Department’s national security section.
